Before you begin

Turn off the computer, disconnect all cables, and transfer the computer to a clear, flat, stable work surface over a non-carpeted floor. Disconnect the modem cable before you disconnect the power cord.

HP strongly recommends the use of an anti-static wrist strap and a conductive foam pad when working on the computer.

warning:

The edges of metal panels can cut skin. Be careful not to slide skin along any interior metal edge of the computer.

caution:

This product contains components that can be damaged by electrostatic discharge (ESD). To reduce the chance of ESD damage, work over a noncarpeted floor, use a static dissipative work surface (such as a conductive foam pad), and wear an ESD wrist strap connected to a grounded surface.
